Application filed February 18, 1910. Serial No. 544,563.

I To all whom it may concern:

Be it known that I, MORTON HAVENS, J r., a citizen of the United States,residing at Albany, in the county of Albany and State of New York, haveinvented certain new and useful Improvements in Conduit-Fittings, ofwhich the following is a specification.

This invention relates to improvements in service entrance conduitfittings, and has for its object to provide a simple, strong, convenientand inexpensive fitting of the class, adapted especially for mountingupon the outside of a dwelling or shop for receiving, supporting andprotecting service entrance wires employed for low potential electricinstallations, such as domestic lighting, or where but one or twoconsumers are to be served with the electric power for lightmanufacturing or lighting.

A particular object is to provide a light serviceable fittin comprisingbut two parts formed-up out 0 sheet metal, and constructed and arrangedto shed water, as well as, to rotect the wires from abrasion.

ther features and parts of the device will be understood from the detaildescription which follows, and by reference to the accompanying drawingwhich forms a part of this specification, and in which Figure l is afront elevation of the complete device, showing wires in place. Fig. 2is a side elevation of' same. Fig. 3 is a top plan View of the fitting.Fig. 4 is a bottom plan View of the same. Fig. 5 is a central verticallongitudinal section on line 5-5 of Fig. 1, showing the construction andarrangement of the parts of the fitting. Fig. 6 is a View, showing amodified form of clamping piece. Fig. 7 is a detail view 0 theinterlocking clamping piece. 1

Similar numerals of reference are assigned to corresponding partsthroughout the several views.

The present invention consists of a twopart fitting for mounting uponthe receiving end of an electric conduit pipe, which may be located inany convenient manner on the side of a building or other support.

The purposes of the fitting are to afford means for receiving andsupporting the branch wires which connect the mains with local lightingor power circuits, for preventing moisture from entering the conduitpipe, and for protecting the wires from abrasion, short circuits andgrounds.

In the drawing, 2 represents the main part of the fitting, and 3 acoacting clamping member, each of said parts being made of sheet metal.The main part 2 consists of an enlarged overhanging dome portion 4,

-which is provided at its front and at its opposite sides with amarginal flange 5 bent upwardly toward its outer edge forming anupwardly opening groove or trough 6, which skirts the front and the twoopposite sides of the portion 4 and is open at opposite ends at 7 at therear of the portion 4 to discharge water or moisture rearwardly at eachside of said portion. The rear side of the body 2 is provided with anintegral depending portion 9, arranged substantially at right angles tothe top 4, and formed with a forwardly facing vertical groove 10arranged centrally with the body. The depending portion 9, which is thussubstantially semicylindrical, merges at its top into the rear surfacesof the dome portion and terminates at its side edges in upright lateralflanges or lugs 11 and 12 which are united at their tops to the rearends of the flange 5 and form continuations of said flange, the rearfaces of the lugs 11 and 12 being arranged substantially flush with theends of the groove or trough 6.

The lug 11 is slotted at 13, and the lug 12 has a threaded perforation14:, for affording means for mounting the clamping piece 3. The mainpart tis provided with an internal chamber 15 arranged beneath the domeand inclosed by the flange 5 and trough 6, which chamber increases inwidth, and the top intermediate portion thereof is concavo-convex incross-section. The chamber 15 has a large mouth which faces downwardlyand is arranged for receiving and protecting branch electric wires whichapproach the fitting on their way from the mains to a building.

The clamping member 3, is substantially semi-cylindrical incross-section, the lengthwise groove 16 thereof being complemental tothe groove 10 of the depending portion 9. The lower part oi. the member3 is of greater diameter than the intermediate part of said member andterminates at its sides in upright lateral flanges 17, 17 correspondingto and opposed to the lugs or flanges 11 and 12 of the depending part 9.The upper ends of the flanges 17, 17 normally coact with the contiguousunder-surface of the rear ends of the marginal flange 5 for facilitatingthe positioning of the clamping memher. One of the flanges 17 isprovided with a Z-shaped ear 18 for interlocking with the slot 13 of thelug 11, as best seen in Figs. 4 and 7. The other flange 17 is providedwith an car 19 perforated at 20 to receive a screw or bolt 21 which maybe screwed into the perforation 14 of the lug 12 for adjustably mountingthe member 3 upon the depending part 9.

The middle upper part of the clamping member 3 is bent inwardly orcontracted in a manner to form on its inner face a stopshoulder 22 forthe upper end of a conduit pipe 23. The arrangement of the clampingpiece 3 and the depending portion 9 of the body is such, that when theformer is mounted upon the latter, the grooves 10 and 16 provide asubstantially cylindrical opening for receiving the end of the conduit23, which may be rigidly clamped and held in position in the grooves bythe tightening up of the screw 21. All of these parts are positioned soas to be sheltered and protected from the weather by the overhangingpart 4c of the body, as shown. The extreme upper end of the clamp 3 isdeflected or extended outwardly to provide a curved rim 24, over whichthe wires, as 25, pass on entering the fitting for connecting with theconduit or local circuit. The upper portion of the clamping member ispreferably corrugated as shown in Fig. 5, in order to suitablystrengthen the rim 24 which supports the weight and strain of the wires,the rim itself being slightly rolled for presenting a smooth androunding surface to prevent the chafing of the wires. The rim 2st of theclamping member preferably extends upwardly into the chamber 15, wherebythe end of the conduit pipe is protected from moisture by the enlargedover-hanging front of the main part 4:. Under this construct-ion of thedevice, the wires must be deflected or bent upwardly in order to enterthe chamber and be inserted into the opening formed by the grooves ofthe depending portions 39. From this arrangement of the said parts, itwill be seen that, water falling upon the wires will be prevented fromfollowing them into the chamber. 26 represents a clamp for securing theconduit 23 to a support, as 27.

Fig. 6 illustrates a modification of the clamping member 3, in whichboth of the flanges 17, 17" are formed alike and arranged to coincidewith, and to be secured to the lugs 11 and 12 of part 9, by two screws21, the lug 11 in this view being perforated and threaded the same aslug 12.

The entire device is preferably made of sheet metal, stamped orformed-up out of two pieces of metal of comparatively light gage, forproducing a low priced fitting. At the same time owing to the peculiarshape or form given each of the parts, the device possesses greatstrength.

My service entrance fitting is extremely simple, strong and inexpensive.Its construction and arrangement are such as to adapt the device forbeing readily and quickly, as well as, rigidly applied to a conduitpipe, either before or after the pipe has been attached to a building.The provision of the domed top and the gutter (3 for shedding anddischarging the water so as to prevent its entry into the chamber orconduit, together with the internal arrangement of the wire receivingchamber, and the novel and simple means for clamping the fitting to aconduit and also forming a supporting rim for the wires constitute thenew and valuable features of the device, which obviously may be changedor modified in some of its parts, within the scope as defined by theappended claims, without departing from the principles or spirit of theinvention.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. A service entrance conduit fitting consisting of two members, onebeing composed of a single piece of sheet metal and comprising anoverhanging dome port-ion and a depending portion, the dome portiondecreasing rearwardly in width and being provided with a marginal flangeat its front and at its opposite sides, the flange being bent upwardlytoward its outer edge forming an upwardly opening groove open at itsopposite ends at the rear of the dome portion, and the depending portionbeing substantially semi-cylindrical in crosssection with its lengthwisegroove facing forwardly, said depending portion merging at its top intothe rear surfaces of the dome portion and terminating at its side edgesin upright lateral flanges secured to the other member and united attheir tops to the rear ends of the marginal flange at the front and theopposite sides of the dome portion, said lateral flanges formingcontinuations of said marginal flange, and the rear faces of the uprightflanges being arranged substantially flush with said opposite ends ofthe upwardly opening groove, substantially as and for the purposedescribed.
